For the first problem change 11 min to seconds by multiplying by 60. Because there is 60 seconds in one minute. 11 min. * (60 sec./1 min) = 660 sec. So for 30 sec. commercial 660/30 = 22 commercial For 60 sec. commercial 660/60 = 11 commercial

One way it helps to look at roots of 3rd degree is that it's the same as the what is under the root to the power of (1/3). Ex: (3√x)= x^(1/3) I would then do this with a higher polynomial like (3√x^5)= (x^5)^(1/3) = x^(5/3)
